I would imagine the 10-50hz sub will be at least $1k itself, probably more like $1500. You need big drivers with lots of excursion to get the deep stuff.

The only thing I don't like about the MBM is that it runs mono up to 150hz. A pair could retain stereo down to 50hz, which is a pretty good setup. Someone bring a pair over so I can test them

Why would you use the MBM above, say 80 Hz, unless your main speakers are *really* small?

The idea of retaining stereo down to 50 Hz is nice, although then you'd probably want them placed up on the front stage by the mains, rather than near field, to take advantage of whatever stereo imaging you're gaining. I think that would probably work well, but you'd have a complicated signal path.

I have dual UFW-10's running in stereo in a secondary setup, and while it's fun, there are a lot of wires back there

True. The separate module (which covers from 50 to 150Hz) was working in conjunction with the new subs. The gunshots in the showdown in "Open Range" felt like gut punches. Unbelievable combination of output AND extension...

John, this would be true assuming that we had actually bothered to turn on the MBM-12 during the demo...

On a positive note, there is so many greats subs here and comming out the world should praise pioneers of sub bass like Dr. Hsu. He is in the elite and because of him the competition has to rethink and redesign, or look bad with underperforming subs.

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

Miracles,are you one of those bible fanatics !? Stone age,yes miracles belong in the ancient times,when looney houses did not exist.

Reproducing very deep bass at serious SPL demands moving air,lots of it. No miracle will help,just curious to see.

Next time try to be informative and play Mr Po Lice less.

Miracles like how you and I are communicating for example.

Airplanes, cars, medicine etc....

200 years ago these things would of been called miracles.

Yet to us today these things are normal - we take these things for granted.

Next time YOU try to be more open minded (and indeed more informative yourself before you write) instead of telling us what IS possible. There was nothing informative about your post except telling us that something is NOT POSSIBLE

You are not the last word in woofer design. Having dozens of speakers don't make you an expert.

In fact you are not a designer period.

Yet you try sounding like an expert.

All I tried to say is that I appreciate people who come up with products that people like you say are not possible.
Have you ever seen the first computer that was ever built?

Dozen speakers? I doubt if he even own a single piece of serious gear.
Some el cheap/DIY ware?
Maybe.......

I own Krell,TenorAudio,JL Audio,TC Sounds,Pioneer Elite,Anthem,SimAudio,Dynaudio,Revel ,Bryston,Aerial Acoustics,Sunfire among others...yes you are correct no serious gear at all. Child your attack is not even one ! Do better. And next time attack me in PM's not on a open forum.

If you aspiring Mensa bright bulbs have read anything I posted you would see I have not atatcked Dr. Hsu,or his subs. His products are great for the price and size. Never said they were not performers.

What I despise is blind fanboys of any company. Who cannot even accept anyone questioning claims,or giving an opinion. Josef Stalin would be proud of you boys.

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

Well, put it this way, until there is some revolutionary new invention that moves air at low frequencies that is not based on a traditional speaker, physics of that configuration still applies.

So, unless the enclosure is larger, the driver is larger, more power is added, there is more port area available, etc., having high SPLs AND being flat to 10Hz requires compromises in design. It is plain and simple, no miracles here.

If Dr. Hsu designed a new device that can accomplish this task without any of the above then he is the god of bass.

No new technology was used IMO,so far Dr. Hsu used very traditional methods,simply he applies them like few designers.And gets the outmost ,maximum out of them.

The sub is A , using very long ports. 10Hz tune would take ...ports on the loooong side,nah. Or B using a PR(multiple)PR's here you can obtain very low tuning and remain in a "compact" box.

All designs are one form or another of compromise. Simply some pick the balance alot better.

We will know when the sub is released,someone will buy it and open one up,and say that is all !!

I bet this unit will be the ideal mate of the MBM. Extreme depth and slam.

I'm very bummed as I only ended up having 6 hrs in Vegas at the CES. I never got the time to get over to THE SHOW (St. Tropez) as my plane was badly delayed due to bad weather. I really would have liked to have heard Dr Hsu's new prototype. One thing that I heard from Hsu booth visitors was that this new prototype doesn't need the MBM.

Its no use people speculating because its just guesswork.
Its a prototype that doesn't even have a spec sheet, model number, release date, let alone a price.

I'm sure if Dr Hsu said its "flat to 10Hz" then its guaranteed to be flat to 10Hz.
Knowing and owning many Hsu subs (both past and present) I have little doubt it will have very good output across its whole operational range.
